I think if you have reached the stage of thinking about gambling strategies while sleeping then you are already categorized as a moderate to heavy gambling addict. Mild addiction will only make you want to gamble when you see your friend gambling or something is affecting you and won't make you think about gambling when you want to sleep.

I love to gamble but I wouldn't spend more than 20% of my income on it. Gambling is indeed profitable, detrimental and also fun but if we do not have good control then everything will end in a sad way. Gambling is not just about winning or losing, but this will be far more fatal when they are not able to control their desire and money in gambling. There is no need to stop gambling if they are still capable enough to control and make themselves responsible gamblers. Just limit your money and desire to gamble and it will be fine.
